IBM Sametime Forum

hi, i'm having a problem with sametime media manager server.
apareantly, client's can't connect to media manager.
following the slide of Frank Altenburg, (http://www.slideshare.net/FrankAltenburg/ibm-sametime-852-installation-from-zero-to-hero-basics) the problem is on page 544, on audio and video service provider doesn't appear "sametime audio/video conferencing".
I must say, i don't have sametime advanced server.
at this part, everything went well, with no problems.
i don't know where to look, and what can it be.
if anyone could help me i would appreciate.
